i Y to provide an accessory of the indicated char- Y acter which eliminates the present prac-tice of storing the media 1n separate containers,

Y such as test tubes, etc., which necessitatesdouble handling; to reduce the danger of contamination to the inoculated surface during plating and subsequent picking of the colo-nies; to admit of the preservation for a substantial period of time of the more important colonies merely by capping the bottle; -to make for less likelihood of breakage of the containers while rendering cleansing more facile; to permit ofthe use of the same bottle for culturing` organisms in broth,

etc., and to provide containers of this character which require less room than flasks of a corresponding capacity while admitting of a compact storage or packingof a number of said bottles. l

The invention further resides in the provision of a culture bottle which is simple in `its construction, which may be inexpensively produced and which is highly eilicient in its purpose.

With the above recited and other Vobjectsy in view, reference is had to the following description and accompanying drawing, in which there is exhibited one example or embodiment of the invention, while the claims define the actual scopeof the same.

ln the drawing:

Figure l is a side elevationof the bottle-as viewed from the left in Figure 2.

Figure 2 is an edge view of thebottle.

Figure 3 is a longitudinal `sectional view through the bottle, illustrating the same sup-V ported on its side in al position to retain the contents.

Referring to the drawing by characters of 1932. 'serial No. slugs/.1.5.`

reference, the bottle embodies a substantially rectangular body including flat parallelA major sides fand 6 and parallel minor sidesv 7 and 8, va bottom 9 and a neck having substantially parallel major sides 11 and l2, one

of which sides, namely, the side v12, is dis-4 posed flush or in the same'plane with the major side wall 6 of the body, and the other of which, namely', the side l1, is odset inwardly with respect to the major side 5 of the body. The vneck is further provided:

with minor sides .13 and 14 which converge from'their juncture with the minor sides ,7V

and 8of the bottle body'to their juncture with the mouth l5 ofthe neck. This `construction of the bottle provides a downwardly Y oif'set chamber or portion A when the bottle is disposed horizontallywith the major side wall 5 downwardly, whether rested on said side 5 or otherwise supported.v The bottle is further provided on at least one of the side Y nearly. parallel and perfect asis feasibletol prevent optical distortion whenv making observations. By constructing the neck of a tapering or flaring configuration, it is possi-V ble to work or pick the colonies with a-suitauf able instrument inserted through the mouth l 15`1o'f the neck. Y

' -While there has been illustrated anddef scribed a preferred embodiment of the inven# tion, no limitation is necessarily intended tothe precise structural details, which it is `un derstood may .be modified within the scope of the appended claims. 'I

What is claimed is:

l. A bacteriological culture bottle including a body having parallel major side walls, a neckv offset laterally with respect to one of said side walls whereby said wall,` and the adjacent walls of the bottle provide a p0rtion for receiving and retaining a fluid plating media when the bottle is supported horizontally on said side.

2. A bacteriological culture bottle including a body having parallel major side walls, a neck offset laterally with respect to one of said side walls whereby said wall, and the adjacent walls of the bottle provide a portion for receiving and retaining a fluid plating media when the bottle is supported horizon? tally on said side and gage means provided on one of the side walls of the bottle and spaced from the bottom for indicating the volume. of, plating media which will be accommodated by the receiving and retaining portion.

3. A container of the character described including a body and a neck offset with respect to one side wall only, whereby said side wall, together with the adjacent wall of thel bottle, deiines when the container` is disposed horizontally on said side wall, a portion for retaining a predetermined volume.

1l. A container of the character described including a `body and a neck offset with re- Spect toy at least one side wall of the body; whereby said side Walls, together with the adjacent Walls of the bottle, defines when the container is disposed horizontally on said side wall, a portion for retaining a predetermined volume and means functioning when the container is upright, for indicating that Y level of the contents which corresponds to said predetermined volume.

5. A container of the indicated characterincluding a body, a neck offset with respect to one of the side walls of the body wherebysaid side wall and the adjacent: walls of the bottle provide a portion for retention of*- the fluid contents therein, when the container is disposed horizontally with said side wall downward and indicating means spaced from the bottom of the body when the container is upright, to disclose the volume of the contents which will be accommodated and re-. tained by said portion.

6. ln a bacteriological culture bottle, asub-V stantiallyrectangular body including flatparallelv major and minor side walls, a bottom and a neck tapering from the minor sidewalls toward the mouth of the neck and havingsubstantially parallel opposite walls, one of which is flush with one of the major side walls and the other of which walls is offset with respect tothe other body side wall, to define in the body a portion for receiving and retaining a uid plating mediaV when the bottle is supported horizontally on said latter offset major side wall of the body. f Y
